What problem does it solve?
Detects fine-grained visual differences between a reference design image and an implementation screenshot so designers and QA can catch regressions or unintended UI changes before release.
Core Features & Use Cases
- Pixel-accurate image comparison that generates a visual overlay marking changed pixels.
- Automatic handling of resolution mismatches by resizing, configurable pixel-difference threshold, and selectable highlight color.
- Outputs a diff image and a JSON summary with total pixels, diff pixel count, percentage, and diff regions for reporting and triage.
- Use cases include comparing Figma exports to live pages, verifying CSS changes, and tracking UI variations across versions.
Quick Start
Run the pixel-diff script with the design image as image_a and the implementation screenshot as image_b to produce diff.png and a JSON summary.
